Via Trend Hunter comes this story about a service called Luggage Club.
I don't travel very much at all, and when I do, I try to take only carry-on luggage. However, with all the hassle that seems to have been added to airline use over the last few years, I could see how this would be really useful.
The idea is that they pick up your luggage from one place and deliver it to another, at a pre-defined time. They obviously use the airlines, too, but the important thing is that it's not you who goes through all the pain.
Goodness knows how much it costs, of course, but what price convenience, I say!
